Sanding Walls And Ceilings; Changing The Sanding Disc; Adjusting Operating Length; Storage - Menzer LHS 225 VARIO Manual Original

Shutting off:
Set the power switch to "O". The sanding disc will continue to spin for a few moments. Make sure that the
machine has finished rotating before you put it aside or set it down.
Setting rotation speed:
Rotation speed is fully variable and can be adjusted as required using the rotation speed controller. This is
also possible while the machine is in operation. A higher rotation speed allows for a higher rate of surface
removal, while a lower speed provides greater control of the surface treatment.

3.2.3 Sanding walls and ceilings

Be sure to hold the sander with both hands at all times.
When starting to sand, carefully place the sander on the desired surface. Apply only enough pressure so
that the sanding head remains flat and is resting on the surface. Applying too much pressure can produce
spiral-shaped scratches and uneven areas in the surface and may also cause damage to the tool itself. It is
recommended that you move the sanding head over the surface using a circular motion. The sander should
be moved continually, as sanding too long in one area can leave behind unwanted marks.

3.2.4 Changing the sanding disc

Remove the sander from the power supply before changing the sanding disc. Peel the used sanding disc
from the hook-and-loop pad and place the new disc in a central position. The sanding disc will be held in
place by the hook and loop system. Choose a suitable grit for your job. Beware that grits that are too rough
reduce your control of the surface treatment, whereas grits that are too fine cause excessive wear and tear
to abrasives.

3.2.5 Adjusting operating length

The operating length of the MENZER LHS 225 VARIO can be freely adjusted to between 1,350 and 1,900 mm.
To do this, loosen the locking ring on the main tube until you are able to pull the telescopic tube inwards or
outwards. Set your desired operating length and turn the locking ring until it is tightly in place.

4. STORAGE

The machine must not be exposed to wet or damp storage conditions. The power cable must be removed
from the power source before storage. It must not be used to hang the tool. Always store the sander in its
carry bag and keep it out of the reach of children.

5. MAINTENANCE

All air passages and joints must be kept free of dirt and cleaned with compressed air after each use of the
machine. Wear protective goggles when doing this. Plastic parts should be cleaned with a soft, damp towel.
Never use solvents for cleaning purposes.

5.2 REPLACING THE SANDING WHEEL

Ensure that the sander is not plugged into a power source. Dust residue should be removed from the wheel
(e.g. by using compressed air). Grip the sanding wheel together with its housing. Hold the threaded axle in
the middle of the sanding wheel in place using an Allen key. The sanding wheel can now be turned anticlock-
wise and removed from the threaded axle.

5.3 REPLACING THE BRUSH RIM

The sanding head is surrounded by a brush rim. This ensures that the majority of the dust collected remains
within the sanding head and can be extracted by the connected industrial vacuum cleaner. If the brush rim
becomes worn or damaged it must be replaced.
To replace the brush rim, first detach the abrasive from the sanding wheel. Remove the screws holding the
brush rim in place and then remove the brush rim itself. Attach the new brush rim and fasten it in place using
the same screws. You can now re-attach the abrasive.
Correction
Fasten the sanding wheel and
disc correctly
(in a central position).
1. Clean the suction system.
2. Empty the bag.
Apply less pressure
when using the machine.
